Abstract

By employing pyridine–nHF solution, the photo-induced fluorinative decomposition of arenediazonium salts (ArN2BF4)(fluoro-dediazoniation) and the related compounds, such as quinonediazides and triazenes, has been successfully carried out to produce the corresponding aromatic fluorides (ArF) in good yields. The rate in the fluoro-dediazoniation of para-substituted ArN2BF4 in pyridine–nHF solution did not obey the classical Hammett ...
